The goal isn't for you to think that explicitly. The goal is for you to subtly associate Product B with feelings related to "young and attractive partner" so that next time you're making a decision between Product B and the competitor's Product C, you are emotionally tilted in their direction. It's probably not enough of a tilt to overcome many logistical factors, but it might also not be something you notice when making the decision.
